Mosfet reverse conduction
WebMOSFET in forward conduction is always higher than the reverse conduction one. When the gate bias is nominal (VGS = 20V), there is still a significant difference between drain … WebIn most power MOSFETs the N+ source and P-body junction are shorted through source metallization to avoid accidental turn-on of the parasitic bipolar transistor. When no bias …
